BackgroundMegaloblastic Anemia (MA) is a relatively common disease, yet the data on prevalence of MA remains scarce. This study was conducted to study the prevalence and clinico-hematological profile of MA.MethodsThis was a cross-sectional study done on 1150 adult anemic patients. All patients diagnosed to have MA were studied for clinico-hematological and etiological profile. Nerve conduction studies (NCS) were done in all.ResultsMA was present in 3.6% cases of anemia. Severe anemia was seen in 9.7% of anemic patients and 75% of MA cases (p<0.05). Forty five percent of MA patients presented with pancytopenia. Vitamin B12 and folic acid deficiency were documented in 40% and 25% cases respectively while combined deficiency was noted in 35% of all MA cases. There was no co-relation between severity of anemia and deficiency of either of the vitamins (Fischer exact test: 0.530). Among MA patients, 35% were vegetarians while 65% consumed mixed diet. There was no association between vegetarian diet and Vit B12 deficiency (p=0.3137). An additional etiology was more commonly found in patients on mixed diet [92%; 24/26] as compared to those on vegetarian diet [50%; 7/14] (p=0.04). NCS was abnormal in 14 patients (35%). Overt clinical neuropathy was present in 12 cases of MA, while subclinical neuropathy was seen in 2 cases.ConclusionMA is one of common causes of pancytopenia and severe anemia. Diet plays an important role in causation of MA in vegetarians. An alternative etiology is however, more likely to be found in patients on mixed diet. While overt neurological abnormalities are common in MA, subclinical neuropathy is uncommon.
